MEANS TO SPRINKLE CRUDE OIL ON DUSTY ROADS.

Specification of Letters Patent.

Application filed May 3, 1905. Serial No. 258,722.

To all whom it may concern:

Be it known that I, JOHN F. BLUNT, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented new and useful Improvements in Means toSprinkle Crude Oil on Dusty Roads, of which the following is aspecification.

In sprinkling crude oil on the streets to lay the dust it is found thatin the ordinary apparatus used for that purpose proper control of theoil is not had, and as a result the oil is often spread upon thesidewalk and curb,

which is very objectionable; and the object of my invention is toprovide practical means to control the disposition of the oil over thesurface to be oiled, to limit the area over which it is spread, toprovide means whereby a sufficiency of oil can be spread over the entireroad-bed adjacent to the curb and not to deposit the oil on the curb orthe sidewalk and at same time to discharge same so close to the surfaceas to prevent the wind from blowing the oil as it falls in fine spray orthin sheets from the oiler to the road-bed, to provide means moreuniformly to distribute the oil over the surface to be oiled, andthereby to economize in the use of oil, and to prevent the deposit of anunusual and unnecessary amount of oil in places on the road-bed,resulting in objectionable puddles of oil in places in the road. Iaccomplish these objects by means of the device described herein, andshown in the accompanying drawings, in which Figure 1 is a sideelevation of the rear end of an oil-sprinklin wagon, showing theoilsprinkler in side efevation. Fig. 2 is a rear view of the cylindricaloil-sprinkler and the rearwardly-projecting apron, the apron beingpartly broken away. Fig. 3 is a transverse section of the sprinkler,taken on the line 3 3 of Fig. 2. Fig. 4 is a rear elevation of thethree-way fitting to which the difierent subdivisions of the sprinklerare in communication.

In the drawings, A represents the usual oil-tank used for sprinklingcrude oil on dusty roads, from which projects rearwardly theoil-discharge ipe B, which carries on its outer rear en the three-wayfitting C, each branch projecting therefrom having cut-off valves Dmounted thereon. A flexible connecting pipe or conduit E connects eachbranch to the nipple F 0L. the cylindrical sprinkler G. On the rear sideof the cylindrical sprinkler are a number of perforations H, providingdischarge-ports through which the oil is discharged. The oil in passingthrough these ports if the tank is full will be projected outwardly insmall jets and con tact with the apron I, secured to the cylindricalsprinkler just above the oil-discharge ports therein. This apron isdisposed thereon so as to pass in close proximity to the sur face of theground beingsprinkled and will limit the area over which the oil isdistributed and prevent its being thrown beyond the 10- cality desiredto be sprinkled and prevent the oil from being blown by the wind uponpassers-by and wasted.

The connecting-duct E bein flexible will provide means whereby the oiferwill at all times move along in close proximity to the surface beingoiled, thereby affording means uniformly to distribute the oil overuneven places in the road-bed.

Road beds as usually constructed are more or less inclined as theyapproach the curband depart more or less from a level adjacent to thecurb. To prevent the oil from running to the lower end of the oiler anddepositing an excess of oil next to the curb, I have divided thesprinkler into a number of subdivisions 1, 2, and 3 by means of thepartitions J. (Shown in dotted lines in Fig. 2.)

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

1. Means for sprinkling crude oil on dusty roads comprising incombination a portable oil-tank; adischarge-pipe leading therefrom; A

a sprinkling-cylinder carrying an apron and having connecting-nipplesand flexible connection solely connecting the discharge-pipe with thenipples.

2. In combination with a portable oilsprinkling tank a cylindrical oilsprinkler having discharge-ports in the side walls thereof; an apronprojecting from the sprinkler at a point on the cylinder above the portstherein, the sprinkler being connected with the discharge-pipe of thetank solely by a flexible connection.

3. In an apparatus for sprinkling crude oil on road-beds comprising aportable oiltank, a sprinkler having discharge-ports therein and adeflectingapron disposed on said sprinkler above said oil-ports andadapted to divert the jets of oil downwardly the said sprinkler being incommunication with the oil-tank solely by means of flexible connections.

4. In an oil-sprinkler of the character herein described a portableoil-tank, a sprinkler provided with discharge-ports in the side thereofand having an apron disposed above said ports closed at the tops andside and open at the bottom, and flexible tubing constituting thesole'connection between tank and sprinkler.

5. The herein-described means to distribute crude oil evenly over unevensurfaces in the road-bed to be sprinkled comprising a portable oil-tanka sprinkler in communication with the oil-tank. by means of flexibleconnections; and having a defiecting-apron disposed on said sprinklerand adapted to divert the jets of oil proceeding from the sprinklerdownwardly in a thin sheet where the surface is being oiled.

6. The herein-described means to distribute crude oil on dusty roadscomprising in combination the oil-tank A having secured thereto thedischarge-pipe B carrying the three-Way fitting C; a valve D on eachbranch of said fitting and the cylindrical sprinkler G having nipples Fthereon; the said nipples being in communication with the three-Wayfitting C by means of the flexible connections E, the said cylindricalsprinkler bein provided with discharge-ports H and the deflecting-apronI disposed on said sprinkler above the discharge-ports and adapted todivert the jets of oil ejected through the discharge-ports downwardly ina uniform sheet.

In witness that I claim the foregoing I have hereunto subscribed my namethis 26th day of April, 1905.

- JOHN F. BLUNT.
